Answer 1

Use dtpDate ValueChanged event to set the value for other two DTP Control.

To set default value, you can use

dtpdate.Value = now.date()

Hi,

You can read or write that is GET or SET the DATE of a DateTimePicker like this.>>

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        My.Application.ChangeCulture("en-Us")
        My.Application.ChangeUICulture("en-Us")
        dtpFrom.Value = Convert.ToDateTime("02/15/2012 12:00AM")
        dtpTo.Value = Convert.ToDateTime("02/15/2012 12:00AM")

    End Sub

Just to show what Amit Goval is saying above try this.>>

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        My.Application.ChangeCulture("en-Us")
        My.Application.ChangeUICulture("en-Us")

    End Sub

    Private Sub dtpDate_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles dtpDate.ValueChanged

        dtpFrom.Value = Convert.ToDateTime(dtpDate.Value.ToLongDateString & " 12:00AM")
        dtpTo.Value = Convert.ToDateTime(dtpDate.Value.ToLongDateString & " 12:00AM")

    End Sub

End Class

Answer 6

sir John Anthony Oliver

another question do you know how to filter the datagrid view? im thinking of, the data that will only show in the datagridview depends on the date selected on the dtpDate.

example if the value of Date is march 20 2012 the data that will only show on the datagrid view is the event that is save on the march 20 2012. also to arrange it ascending based on time start. thank you and sorry for the trouble =)
